2.19 understand how varying carbon dioxide concentration, light intensity and temperature affect the rate of photosynthesis

Factors affecting the rate of Photosynthesis (Limiting factors of photosynthesis)

1.      Light intensity: As the light intensity increases so does the rate until a plateau is reached.

2.      CO₂ Concentration: As the concentration increases so does the rate until a plateau is reached

3.      Temperature: As the temperature increases so does the rate. However, after an optimal temperature for enzyme activity, they begin to denature causing the rate to decrease.
